9) Finally, the qualified fine powder pass from the classifier, then to be collected by the cyclone. Meanwhile, the unqualified products will fall back to the main mill for regrinding till be qualified.

HDW Series German type improved grinding mill is widely used in the fields of metallurgy,chemical industrial, electric power, oil, and non-metallic mineral processing, etc. The products are mainly used for industrial desulfurization , the interior and exterior wall coatings of the buildings, plastic rubber filling, paper-making, feed supplement and the recycling of slag.

With scientific & reasonable design and its unique advantages,HD DBMW German Type Fine Grinding Mill are applied widely in power, metallurgical, cement, chemical and non-metallic industry, for grinding of various materials, such as cement raw material, clinker, limestone, slag, manganese, gypsum, coal, barite, calcite etc.. The grinding field is wide and grinding type is abundant.

1.Humidity of grinding materials: from materials ofless than 6 %(such as cement clinker), wide range of materials. 2. Grindability of materials: from high grindability(such as quartz sand, steel slag, mining slag, pyrophyllite, iron ore etc.) to low grindability (such as gypsum, calcite, etc). 3. Fineness of grinding product: from 2-5mm(such as raw shale for making brich in new wall material industry, sand for construction industry, etc) Product fineness is easy to adjust and simple operation

4Possibility of main mill housing been cracked is minimal:HD-DBMW Series German Type Grinding Mill assembled with flexible coupling between housing and main mill.When the main mill works, the housing will have no force and vibration . This can help the housing will be strong enough .

1)New technology structure to protect the center shaft. The framework oil seal is installed with new technology structure to protect the center axis. Thus,the center axis of main mill can withstands even the greatest wear and tear

3)To service the oil seal equipment, workers dont need to disassemble the main mill any more. Workers can replace the oil equipment from the repair tank of the reducer. This can save the equipment maintenance time and labor intensity greatly.

HDW Series German Type Fine Powder Grinding Mill has no return air box and no air duct guard plate structure. And the grinding chamber is full of negative pressure. which makes the powdery material in the sealed grinding chamber to be ground perfectly.

The powdery material is ground in the closed grinding chamber. Then the finished powdery material is pumped to the classifier to be classified by the negative pressure . since there is no positive pressure in the lower part of grinding chamber, the powdery material will no be raised in the grinding chamber due to positive pressure.This ensure the effective grinding of powdery material in the grinding chamber.

There are positive pressure air ducts around the base of traditional domestic mill .This makes the powder easy to raise , resulting in less abrasive fabric surface .Since hard materials have low grind-ability , when the grinding mill works, the equipment will subjected to large impact force, fast loss,large vibration, loud noise,fast loos and low output. Thus,HD-DBMW Series German Type Fine Powder Grinding Mill is designed specifically for the whole powder material and hard material ideal model.

Turbine blades of ultra-fin classifier are vertically embedded in upper and lower panels. The blade will not deform will not deform without welding. With equal blade spacing, high classification accuracy and concentrated particle size distribution, it can separate 325-1250 mesh powdery materials.

The turbine of traditional analyzers is inclined and fixed on the upper and lower panels by welding. Due to the large amount of welding ,the turbine produces welding stress and deformation, the blade spacing is not uniform, and the gas dear formed at the top in the labyrinth groove is easy to cause rough running. In order to avoid coarse running, it is necessary to increase the speed and thus affect the output. The particle size distribution of finished products in scattered, so only 80-400 mesh powdery materials can be sorted.
